Dynamic tables within tables do not preserve their values over a save / load

问题

Using Livecycle Designer - now Adobe Experience Manager v 6.4.0.xxx, I'm trying to allow my users to create tables within tables in a form. I'm comfortable with non-nested tables - they work fine. The problem is that when I nest tables they lose information over a save. The first row is saved fine, but subsequent rows are not saved.

These are non-trivial tables. An outer row has, say 5 text fields, some radio buttons, subforms that hide/show based on logic, etc. The nested table only shows under certain logic - it also has multiple text fields and check boxes. However, I've simplified this down below - still fails.

Based on Nested tables in livecycle fall apart on email, I decided to toss out tables and nest subforms to gain the same look and feel as tables. Again, one 'table' built this way works fine, but the subsequent nesting breaks - in interesting/crazy ways - the subform nested in row one gets more rows (instanceManager.count) and subsequent rows lose their textfield information - but radio buttons keep their information.

What I've done

I've rebuilt using subforms over tables. No love, though interesting weirdness.
I've toggled the Form Properties / run-time / Preserve scripting changes to form when saved -- I want automatic but I've toggled to manual and back. (Per https://forums.adobe.com/thread/1281883)
I've monitored it as best I can - on preSave and postSave the information is there - on initialization it's gone.

Pre-Save

Post-Save Totally whacky. Kept second row (unlike tables) but lost the information in fields. First row somehow gained another nested row.

I call this from a button 'click'

function fAddSfRow(oSfTable) {
  oSfRow = oSfTable.sfRow;
  oSfRow.instanceManager.addInstance(1);
}

And, to remove a row - in another button 'click'

var oSfRow = $.parent;
if (oSfRow.instanceManager.count > oSfRow.instanceManager.occur.min ) {
  oSfRow.instanceManager.removeInstance(oSfRow.index);
}

What I'd like is a nested table with text fields in each that saves/loads.

Thanks!!

Okay, the best answer I've found is...

Wrap only the table with inner tables with a 'pre-save' and 'initialize'.

Presave

Capture the number of total rows for the outer table
Capture the number of rows for each inner table
Capture the rawValue of each field
Store all this somewhere - say in a hidden text field

Initialize

Set table.row.instanceManager.count for outer table
Set table.row.instanceManager.count for each row of inner tables
Reset all rawValues for fields
do any logic for hiding/showing subforms or whatever

Ughh.
